Is project documentation an afterthought? Does the documentation stage of a project seem to be a tedious process? Does the customer understand the importance of proper definition? Documentation is likely the most important part of a project.
Project documentation used to define the plant process and functional requirements of the automation system. It will give both the customer and the engineer the opportunity to mentally work through how the system should operate before any code is written. It provides an opportunity for collaboration and review. Proper definition will always make your projects more successful.
